Re: Wheeler Knapp
I believe you might want to check the Roger Knapp Line of Fairfield, Fairfield Co, CT.There is a Wheeler Knapp [no dates or other info]son of James and 1st wife-Eunice(Morehouse)Knapp, with siblings named, Abijah, Huldah, James, Jr, Ezra, Ephraim, Eunice. A daughter Emeline, born to James Knapp's third marriage to Catherine Brothwell.There were no known children born of James second marriage to Mary Brown.
The time from of his 2d & 3d marriage 1782 & ca1787, would indicate this to be your Wheeler Knapp.
James Knapp, was the son of John & Hannah (Jennings) Knapp; John the son of Daniel and Abigail (Banks) Knapp; Daniel the son of Josiah & Sybil (Dickerson) Knapp; Josiah the son of Roger, the immigrant and his unknown first wife.
All data to be found in "History & Genealogy of the Families of Old Fairfield" (1930), by Donald Lines Jacobus, M.A., F.A.S.G., in 3 Volumes.
Good Luck in your search,
